Introduction

Leak Location Services, Inc. (LLSI) is the world leader in geoelectric leak location testing. The technical staff of LLSI have a combined total of more than 86 years of commercial geomembrane leak location experience. LLSI has performed more than 4,269 leak location surveys and surveyed more than 696,887,578 square feet of survey.

LLSI has successfully performed leak location surveys worldwide for more than 33 years. We develop, design and build the specialized equipment required to perform these services. Our highly experienced and trained staff have the in-depth understanding of electrical leak location methods to successfully perform leak location services with the efficiency required to keep your project on time and within the cost proposed.

In 2024, LLSI completed 109 geomembrane leak location surveys. The area surveyed was more than 23,048,190 square feet (529 acres). In the last three years, LLSI has surveyed more than 70,548,800 square feet (1,619 acres) of geomembrane.

LLSI has tested triple-, double-, and single-lined landfills, ponds, lagoons, leach pads, tanks, vaults, highway subgrade, tennis courts, HDPE pipe, and landfill caps, including testing of smooth, textured, and reinforced geomembranes, including HDPE, LLDPE, PVC, XR-5, CSPER, asphalt, polyurethane, and polypropylene.

The LLSI leak location equipment, software, and procedures are custom-designed and fabricated by LLSI to produce unequaled leak detection capabilities. The equipment and procedures have been improved and optimized through 33 years of field applications.

The founders of LLSI began the development of the geoelectric leak location method at Southwest Research Institute in 1980 and the first commercial leak location survey was performed in 1985. Leak Location Services, Inc. was formed in 1992 as a Texas corporation. LLSI owns the exclusive patent rights on the geoelectric leak location method covered by United States patents 5,661,406 and 6,331,778. LLSI has provided leak location services in 48 states, eight Canadian provinces, and 28 foreign countries.
